<p>In GNU C, pointers to arrays with qualifiers work similar to pointers
to other qualified types. For example, a value of type <code class="code">int (*)[5]</code>
can be used to initialize a variable of type <code class="code">const int (*)[5]</code>.
These types are incompatible in ISO C because the <code class="code">const</code> qualifier
is formally attached to the element type of the array and not the
array itself.
